Natural, silicone-free heat protectant for hair
Biolaminar Sealer
Anti-frizz heat protectant that repairs the hair fibre, restoring the hair’s health.
This Biolaminar Sealer has been carefully formulated to restore the hair’s natural beauty by rebuilding its structure, protecting it from heat, and eliminating frizz. Botanical actives such as artichoke leaf, sunflower oil, and rice protein transform the hair fibres by creating a shield around them that locks in hydration without adding weight. The result? Revitalised hair with more movement and shine.
When applying this creamy emulsion lotion, you’ll feel your hair soften in your hands as the aromas of black orchid, cinnamon, and sandalwood are released.

Natural, silicone-free heat protectant for hair
-
Is this heat protectant suitable for all hair types, including fine or coloured hair?
Yes, our Biolaminar Sealer has been formulated to suit all hair types, including the most delicate ones such as fine or coloured hair. Its lightweight texture doesn’t weigh the hair down or leave residue, providing effective protection without compromising the hair’s health or natural movement.
-
Does it protect the hair from the heat of straighteners, dryers, and curling irons?
Yes, it provides a natural barrier against the heat from thermal tools such as straighteners, dryers, and curling irons. It protects the hair fibre from thermal damage thanks to its silicone-free composition, keeping the hair healthy, shiny, and flexible even with frequent heat styling.
-
Does this product help reduce frizz in humid environments?
Yes, it helps control frizz in humid conditions. Its sealing action on the hair cuticle reduces frizz and keeps the hair more manageable, without losing its natural movement or becoming heavy.
-
Does the heat protectant provide hold for styling or only protection?
This product is primarily designed as a heat shield, not a styling gel. It provides protection without stiffness or stickiness, allowing the hairstyle to maintain its shape with a natural look. It can be combined with styling products if longer-lasting hold is desired.
-
Does this heat protectant contain silicones, sulphates, or parabens?
No. Like all Secretos del Agua products, it is formulated without silicones, sulphates, or parabens. Its formula is gentle on the scalp and environmentally friendly, providing clean and conscious protection.
-
How long does the protective effect last after application?
The protective effect remains active throughout heat exposure after being applied to damp or dry hair. There’s no need to reapply it during the day unless you wash your hair again. For continuous protection, it is recommended to use it before each use of heat styling tools.
We cultivate and macerate our botanical actives following the biodynamic calendar. We study biodynamics in relation to beauty rituals to unlock the full potential of the skin and hair. Consult our biodynamic calendar to discover the ideal moment to begin application.
